Question 800718: 2 wheels are attached together by a chain. the radius of 1st wheel is 20 cm and that of the second wheel is 30cm. the 1st wheel revolves 600 times in a minute. how many time will second wheel revolve in the same Time? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 2 wheels are attached together by a chain. the radius of 1st wheel is 20 cm and that of the second wheel is 30cm. the 1st wheel revolves 600 times in a minute. how many time will second wheel revolve in the same Time?
----------------------
circumference of the 1st wheel = pi*d = 20pi cm
In 600 revs the chain would move 600*20pi = 12000pi cm
----
circumference of the 2nd wheel = 30pi cm
---
# of revs of the 2nd wheel would be 12000pi/30pi = 400
